[0002] In the printed matter production workshop, the die-cutting machine is a common equipment. The die-cutting machine cuts the printed matter or the matter to be printed into the required size. When the die-cutting machine uses the rotation of the circular knife to cut, it only needs to If the size of the sheet product is not an integer, it will cause waste of materials
For example, the diameter of the circular knife is 20 cm, and the circumference of the circular knife is 125 cm. When the product needs to be cut every 10 cm, 13 blades need to be installed on the circumference of the circular knife, and the circular knife rotates once to cut 12 pieces of 10 cm. product and a 5cm piece of waste, such reciprocal cutting will cause a lot of waste of material

The invention provides a die-cutting machine provided with a length compensation mechanism. The die-cutting machine provided with the length compensation mechanism comprises a paper feed roller, a paper collection roller, a first paper guide roller and a second paper guide roller, wherein the first paper guide roller and the second paper guide roller are located between the paper feed roller and the paper collection roller. The die-cutting machine provided with the length compensation mechanism further comprises the compensation mechanism which works between the two paper guide rollers and isused for pulling a material back by a certain distance. By adoption of the die-cutting machine provided with the length compensation mechanism, severe material waste is avoided, and the production cost is reduced; and the structure of the compensation mechanism can be accurately controlled through a distance sensor and a servo motor, and thus, the production requirement of products with differentsizes is met.
